IMPROVEMENT PUMPS.

TO ALL WHOM IT MAY CONGERN:

Be it known that I, J. R. WEISIGER, of' Danville, in the county of Boyle, and State of Kentucky, have invented a new and useful Improvement in Pumpsg and I do h ereby declare that the following isa full, clear, and exact description thereof, which will venable others skilled in the art tomake and use the same, reference A.being had to the accompanying drawings, forming part of this'specifieation.

' The present invention consists in so constructing and arranging the various parts composing the pump as to secure a continuous suction, while at the same time the oil or other liquid in which the pump isfworking is being lifted and thrown out or discharged from the pump in a continuous stream. In accompanying lplate of drawings my improvement in pumps is illustrated, the-l Figure 1 beingla central vertical section of the same; and

Fignre asimilar section, but of an addition thereto. V

A, in the drawings', represents the pump-cylinder or tube,` in which is arranged, so'as to moveair-tight, a iston, B, `having a rod, C, attached to it, that plays in and through the centre of a-dskv or plate, D, secured across the inside of the cylinder orytube A, 'at/or near its upper end; the' aperture through this plate, D,'being suitably packedto form an air-'tight joint with the piston-rod` In the cylinder A, at or near its lower end, a ball.` or other suitable valve, G, is placed, opening upwards,'which valve is below the pistonB. Below the valve` G a pipe or tube, H, communicates with the pump-tube orcylinder-A, which pipe extending upward upon the I' outside of the cylinder A, again communicates with the same at a' pointla little below its parti-tion plate D, and above the piston-head. In the pipe or tube H at rnear its lower end, or near the point where it commuiiicatesv with the cylinder A below the valve Gr, a ball or other suitableyalve, I, is placed so' as to opcn upwards. J,

another tube communicating at its lower end with the cylinder A, at a point just above its valve, G. This tube,

J, extends upward outside ot' the cylinder A, and at its upper end again' communicates with the said cylinder A at a point above its partition-plate D. In the tube J a ball or other suitable valve, K, is arranged, at `or near its lower end, which valveop'ens upwards. L, a shortvtube or pipe. communicating at its lower end with the cylinder A just b'elowits partition-plate, D, anda-t its upper end with the said cylinder 'above Vthe said plate D; this tube extending upward and outside of the cylinderA, andbeing provided with a valve, M, atv oi" near its lower end, opening upward.v N, the discharge spout or nozzle o'f the cylinder A, communicating with the same above the partition-plate D.

From the above description of theconstruction and arrangement of the various parts composing the pump, together with the drawing accompanying the same, it 'is plain to be seen that by the ,upland-down movement of .the piston in the cylinder ,or tube A, a continuous suction of the oil or other liquid, in connection with which the pump is arranged to operate, must'take place, while at the same'time the liquid is being lifted or raised and discharged from th'e pump in a continuous stream. In lig. 2 the addition shown consists' in arranging an air? chamber in' the pump-cylinder or barrel A, and in such a manner that it can be thrown into connection with or disconnected from the said barrel according as it is desired to use the same or not, for facilitating-the. operation of the pump this air-chamber, O, being formed by enlarging the pump-barrel, and pntl into or out of connection with the pump-barrel, through a concentric tube or cylinder, P, provided with a screw-thread around its outside, and a collar, Q; the air-chamber being shown in connectioniwith the pump-barrel invig. 2, but being disconnected when the lower end of the screw-tube P is screwed into the screw-socket of the pump-barrel,as is apparent.l v

I claim as new, and desire to secure by Letters Patentv The pump-cylinder or tube A, provided with a piston, B, partition-plate D and valve Gr, in combination with the tubes H J L, having valves I, K, M, respectively, when all arranged with regard to each other so as to operate substantially in the manner and for the purpose described.
